They were overwhelmed by the support of the community during their own fight, and now the family of Billy Caldwell need your help again.

Billy, 12, became the first UK person to be prescribed medicinal cannabis on the NHS this year after a long fight by mum Charlotte.

Now the youngster, from Castlederg in Co Tyrone, is the poster boy for Billy's Bud, the brainchild of a US-based Fermanagh man whose company, 710 Holdings, is manufacturing the specialist cannabis oil in America.

She added: "Just even helping one family, it makes us feel rather proud that a wee family from 'the sticks' could do that."

Billy came to the attention of 710 Holdings when he was treated in Los Angeles for life-threatening epilepsy.

The youngster was dosed with cannabis oil made by the company from plants grown in Nevada and processed in Las Vegas.

710 Holdings will ensure Billy has access to the care he needs for the rest of his life.

Charlotte's campaign, Keep Billy Alive, fought for her to be permitted to bring medicinal cannabis into Ireland and home to Co Tryone.

Just weeks ago their GP prescribed cannabis oil for the youngster on the NHS, setting a precedent for other patients wishing to use the non-psychoactive CBD extract while living with a number of conditions including cancer, MS and chronic pain.
